Specification of Letters Patent.

Patented Dec. 16, 1313.

Application filed March 20, 1912, Serial No. 684,996, Renewed March 13, 1913. Serial No. 754,130.

principal object of the same is to provide a wheel with an improved type of spring construction which is positioned between the hub and the rim so that the jolting caused by going over rough roads will be reduced as much as possible.

This invention is illustrated in the accompanying drawings wherein:

Figure 1 is a side, elevation-of the improved wheel. -Fig. 2 is a horizontal sectional view taken through the wheel. Fig.

3 is a fragmentary view of the spring looked upon the outer clamping plate which assists in holdingthe spring in position. Fig.

4 is an enlarged fragmentary view of the inner portion of the spring clamp. Fig. 5

is a sectionalview along the line.5-5 in Fig. 4. Fig. 6 is a fragmentary edge view of the. hook which is mounted bet-ween the r outer edge portions of the plates carried by the hub Fig. 7 is a plan view of the inner clamping plate used in securing the springs in place.

Referring to the accompanying drawings, it will be seen that this invention comprises a hub 10 which carries a collar 11 and has its opposite end portion reduced to form the shoulder 12 against which the plate 13 fits. Resilient plates 14 which are provided with circumferential corrugations are placed between the collar 11 and plate 13 and are held in place by means of the bolts 15, the space between the plates .14 being filled with any suitable material, such for instance as fiber or the like.

sbence; This hoop. 16 is provided with depressed pockets 19 at each of the inwardly extendin web 20. eing positioned in the bottom ofeach of the pockets 19. A link 21 is mounted in each of the pockets 19-and is provided with bifurcated inner and outer end porthe link 21.

' the plate 33 portions 18 of the plates 14, a. v are secured to the hub and the plates are I y tions so that the inner ends will straddle the web with the arms 22 formed by the bifurcation provided wit-h openings 23 registering with an opening 24 formed in the tongue 20.

A pivot pin 25 has its rectangular central portion mounted in the rectangular opening 24 and its cylindrical outer ends passing through the openings 23 with roller bearings 26 surrounding the outer ends to cause the link to move easily. The arms 27 formed by the bifurcation in the outer end portion of the lirk are provided with cylindrical openings 28 in which the outer end portions of the pivot pin 29 are positioned. Roller bearings 30 are placed around the outer ends of the pivot pin 29 and are held in place by means of the washers 31 and Y securing screws 32.

A clamping plate 33 is provided with a pivot block 34 in which is a rectangular opening 35 in which the rectangular central portion of the pivot pin 29 is mounted, thus pivotally connecting the plate 33 with Perforated side wings 36 ex-"80 tend from the corners of the plate 33 so that securing bolts 37 may be connected with the plate 33.

Afelly 38 which carries a rim 39 surrounds the plates 14 in spaced relation thereto and is provided at points around its circumference with blocks 40 through whichthe bolts 41 pass. felly sitioned in alinement with the clamping plates 33. Springs 43 which have their end portions corrugated have their"- ends bifurcated and mounted upon thebolts 41 and rest upon a bracing plate 44carried by the plate 33. A second bracing plate 45 is positioned upon and a clamping plate 46 is connected with by means of the bolts 37 which pass through its perforated wings 49 and the perforated wings 36 of the plate 33. A web 50 extends from the plate 46 and is provided with a slot 51 through which the curved portion 42 of the arm passes. These;

webs 50 serveto prevent a lateral movement of the rim and hub portion. a

When assembling this device the plates 14 the outer face of the spring 43 pic the hub portion, of course, it being understood that the springs and. plates 33 and links 21 have been secured to the rim and put before the rim is placed, around the hub. The plates 46 are positioned between the springs with the curved portions of the felly fitting in the slots 51. The braces 4.4: and are next placed between the springs of the securing plates and the securing bolts 7 are now passed through the side wings of the securing plates 38 and 46 and the bolts tightened so that the springs will be securely held in place. It willthus be seen that the hub portion of the wheel is suspended in the rim portion by the springs 43, the hub portion and the rim portion being prevented from having relatively lateral movement by means of the webs through which the curved portions 45 of the rim pass. It should also be noted that by having the spring corrugated that there is given a double spring action to each spring, there' being provided the usual spring action of a leaf spring and a longitudinal crimping spring action.

.lt will tlius be seen that there has been provided a spring which is veryeflicient in service and which will give the wheel all the resiliency necessary and still will be perfectly free from breaking and bending.

What I claim is:'

'1. A device of the character described comprising a hub, resilient plates'secured to said hub, a hoop connectin the outer edges (ifsaid resilient plates, lin s pivotally connected with said hoop, a rim, springs carried by said rim, clamping plates pivotally connected with said links and positioned adj acent "the centers of saidrsprings, and bracing webs extending from the outer clamp ing plates and provided with slots in their outer end portions in which said rim is positioned.

2. A wheel comprising a hub, side plates carried by said hub,'a hoop carried by said side plates, said hoop having a pocket formed around its circumference, a web in the bottom of each of said pockets, a link pivotally connected with each of said webs, a clamping plate pivotally connected with each of said links, a rim, springs carried by said rim, a second clamping plate connected with said first mentioned plate and adapted to secure one of said springs adjacent the center thereof, and means carried by said second clamping plate for preventing relative lateral movement of said rim and hub structure.

3, A wheel comprising a hub, a rim surrounding said hub, leaf springs carried by said rim, clamps carried by said springs and pivotally connected wit-h said hub structures, and plates carried by said clamps and havin their outer end portions bifurcated Where y said plates may be slidably connected with said rim. r

4. A wheel comprising a hub structure, a rim surrounding said hub structure, corrugated spring strips carried by sa1d rim, links pivotally connected with said hub structure, clamps pivotally connected with said links and engaging the central portions of said vsprings, and means carried by said clamps for slidably connecting said clamps with said rim.

In testimony whereof I afix my signature in presence of'two witnesses. l
